# Ideas for Progress: Range 16–19

## ACT Explore/ACT Plan/The ACT Mathematics

Entries followed by a dagger (†) apply to the ACT Mathematics Test only.

To enhance their skills in each mathematics-related strand, students who score in the 16–19 score range may benefit from activities that encourage them to do the following:

Basic Operations & Applications solve routine arithmetic problems that involve rates, proportions, and percents model and solve problems that contain verbal and symbolic representations of money do multistep computations with rational numbers interpret data and use appropriate measures of central tendency to find unknown values find the probability of a simple event in a variety of settings gather, organize, display, and analyze data in a variety of ways to use in problem solving conduct simple probability experiments, use a variety of counting techniques (e.g., Venn diagrams, Fundamental Counting Principle, organized lists), and represent results from data using different formats apply elementary number concepts, including identifying patterns pictorially and numerically (e.g., triangular numbers, arithmetic and geometric sequences), ordering numbers, and factoring recognize, identify, and apply field axioms (e.g., commutative) create expressions that model mathematical situations using combinations of symbols and numbers evaluate algebraic expressions and solve multistep first-degree equations sketch and identify line segments, midpoints, intersections, and vertical and horizontal lines describe angles and triangles using mathematical terminology and apply their properties find area and perimeter of a variety of polygons by substituting given values into standard geometric formulas evaluate polynomial functions that use function notation† distinguish between range and domain†
